Abstract
The utility model discloses a bellows compensator, which comprises end unions, a gasket, a bellows, a guide pipe and a pull rod, both ends of the bellows are respectively connected with the end unions, the gasket is mounted on the inner surface of the end union through which fluid first flows, the guide pipe is mounted in the end unions and the bellows and is in contact with the gasket, fixed bases are correspondingly arranged on the end unions of both ends of the bellows, and the pull rod is fixedly connected between the corresponding fixed bases. The bellows compensator is characterized in that: the structure is compact, the size is small, no space is occupied, the bellows compensator can be used in a narrow space, the effective stretching deformation of the bellows is utilized to absorb the change of size caused by thermal expansion and cold contraction or other reasons or to compensate axial, transverse and angular displacements, and the bellows compensator has the effect of reducing noise and vibration.
Description
Technical field
The utility model relates to the compensation device of pipeline, is specifically related to a kind of corrugated expansion joint.
Background technique
Existing corrugated expansion joint mainly contains straighttube-type and bent-tube boiler structure, utilizes many group bellowss to constitute with adapter, pull bar respectively, and its boundary dimension is big, and it is big to take up room, and is difficult to use in narrow and small place, space or the compensation between the main equipment.
The model utility content
The purpose of the utility model is to overcome above-mentioned not enough problem, and a kind of corrugated expansion joint is provided.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of corrugated expansion joint; Comprise pipe nipple, washer plate, bellows, honeycomb duct, pull bar; The two ends of said bellows are connected with said pipe nipple respectively; The internal surface of the pipe nipple that fluid passes through earlier is equipped with said washer plate; Said honeycomb duct is installed in the inside of pipe nipple and bellows and contacts with said washer plate, and correspondence is provided with fixed base on the pipe nipple at said bellows two ends, is fixedly connected by pull bar between the corresponding fixed base.
At least evenly be provided with two fixed bases on the said pipe nipple.
Said fixed base is provided with tapped hole, and said tie rod end is provided with the outside thread that cooperates with said fixed base, and said fixed base and pull bar be through being threaded, and is fixed by nut.
The characteristics of the utility model are: compact structure, volume be little, do not take up room, can be used for small space; Utilize effective dilatation of bellows to absorb the dimensional changes that causes owing to reason such as expand with heat and contract with cold; Or compensating axial, laterally and angular displacement, and has the effect of noise reduction vibration damping.
